High bone mass refers to an increase in the mineral content of the bones. The bones of the human body have a lot of minerals, which are composed of a part of colloidal substances and water. Once the mineral content of the bones is increased, the bones become hardened, the mineral content of the bones increases, the water and colloid content of the bones decreases, the bones become hardened, the brittleness of the bones increases, the toughness of the bones decreases, and fractures are particularly likely to occur. Increased bone mineral content is mostly due to trauma, inflammation, degeneration of bodily functions, infection of bones or bone tumors, or many other diseases or causes. Therefore, once the mineral content of the bones is increased, it is important to seek medical advice to exclude the relevant diseases.
